If you're planning to visit the western coast of France anytime soon, be sure to keep an eye out for a 40-foot-tall mechanical elephant. Perhaps taking inspiration from steampunk fiction and Jules Verne, French engineers, artists and craftspeople have cobbled together a movable mammoth using45 tons worth of reclaimed wood and steel.

And it's not just for decoration: this robust creature can carry up to 49 passengers on a 45-minute walk around the city of Nantes.

Bathrooms may dispose of waste, but they create it, too: The average person flushes the toilet five times a day, using between 8 and 35 gallons of water. Not only that, but Americans each use about 50 pounds of toilet paper every year.

Now, thanks to Tom Broadbent, bathrooms may
start impacting the environment in more positive ways by becoming power generators.
